Abstract

A micro relay includes a base substrate, an armature block, and a cover. The base substrate has an indentation for containing an electromagnetic device. The indentation is formed by a through hole penetrating the base substrate and an indentation cover of thin film attached to one surface of the base substrate so as to close the opening of the hole. The electromagnetic device is isolated from a contact mechanism by the indentation cover, thereby increasing the reliability of the contact. The electromagnetic device includes a yoke, a coil wound around the yoke to generate a magnetic flux in accordance with the excitation current, and a permanent magnet attached to the yoke and generating a magnetic flux passing through the armature and the yoke. By attaching the permanent magnet to the yoke, it is possible to reduce the thickness of the relay.
